Charger Location & DC Connection
14. CHARGER LOCATION
CAUTION
a. Locate the charger as far away from the batteries as possible.
b. Never place a charger directly above a battery being charged; gases or fluids from the
battery will corrode and damage the charger.
c. Do not operate charger in an enclosed area or in an area with restricted ventilation in any way.
d. Never allow battery acid to drip on the charger when reading electrolyte specific gravity
or filling a battery.
e. Do not set a battery on top of charger.
f. Do not install on or over combustible surfaces.
15. DC CONNECTION PRECAUTIONS
CAUTION
a.Connect and disconnect DC output cables only after removing AC cord from electric outlet.

Understanding Battery Types
There are three primary types of batteries: flooded (lead-acid), AGM (Absorbed Glass Mat) and
Gel cell (Gelled electrolyte lead-acid). Traditionally, the most common type of batteries used
are flooded (lead-acid batteries).
Almost all Gel Cell Batteries will state that they are Gel Cell on the battery case or labels.
NOTE: AGM (Absorbed Glass Mat) batteries are not Gel (Gelled electrolyte lead-acid)
batteries. AGM batteries are charged with a completely different charge profile when
compared to Gel batteries.
For use with flooded (lead-acid) or Gel batteries. Not for use with AGM (Absorbed
Glass Matt) or 4D or 8D large capacity batteries.
***If you are unsure as to what kind of battery you have, we recommend that you contact
the manufacturer of the battery.
